Malwarebytes Chameleon can remove malware from an already-infected PC

http://www.malwarebytes.org/

If malware somehow manages to penetrate your PCs defenses then it’s easy to assume you’ll simply download some other antivirus tool to remove it. But life may not be so straightforward. Once installed, some malware will try to prevent you from reaching big antivirus sites, and downloading or running their tools, making the problem much more difficult to tackle.

Unless, that is, you have a copy of Malwarebytes Chameleon to hand.

The program is essentially just a collection of tiny portable tools, each of which aims to do the same thing: download Malwarebytes Anti-Malware, install it, launch the program and kill any known malicious processes. And it does all of this automatically, with no problems, no folder selections, no license agreements or anything else, making Chameleon extremely easy to use.
